Most paint failures trace back to prep, not the paint. Here are the common problems, their causes, and the early sign a repaint is coming. Prep well and the finish lasts.
01.
Painting over dirty, damp, or unprimed surfaces. Or moisture pushing from behind the wall.
Paint lifting at edges, bubbling, or flaking in sheets. Often near baths or exterior trim.
02.
Too many thick coats, mismatched layers, or age stiffening the film.
A web of fine cracks like alligator skin, usually on old exterior or trim paint.
03.
Painting in direct heat or over a damp surface, trapping moisture or air under the film.
Small raised bubbles soon after painting, especially in sun or humidity.
04.
Uneven application, a dry edge, or the wrong nap roller for the surface.
Visible streaks, stipple, or darker overlap lines in raking light.
05.
Sun and low-grade paint break down the binder over time.
Color that dulls, or a chalky residue on your hand from exterior paint.
06.
Water, smoke, tannin, or marker bleeds up through paint with no stain-blocking primer.
Yellow or brown blotches reappearing through fresh paint within days.
